JOHN GREER, OF GREENSBOROUGH, NORTH CAROLINA.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 484,195, dated October 11, 1892.

Application filed January 20, 1892. Serial No- 418,653. (No model.)

To all whom it may concern.-

Be it known that I, JOHN GREER, of Greensborough, in the county of Guilford and State of North Carolina, have invented certain new and useful Improvements in Lnbricators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

Myinvention relates to an improvement in lubricators; and it consists of a hanger having a rounded lower end, and which is formed with a vertical oil-passage, and an oscillating oiler having a vertical passage and a rounded depression in its upper end, which fits the lower end of the hanger, and a vertical spring which is secured to the said hanger and oiler and which holds them normally in line, all of which will be more fully described hereinafter, and more particularly referred to in the claims.

The object of my invention is to provide an automatic oiler for the wrist-pins of drivingwheels and other crank-bearings which will lubricate the same while the said bearings are in motion, but in which the oil-supply will be shut 01f when the said bearings are at a standstill.

Referring to the accompanying drawings, Figure 1 is an elevation of my improved lubricator. Fig. 2 is an edge View of the same. Fig. is a detached view of the pivotal bolt E.

A represents a hanger, which is supported on the lower end of the supply-pipe B, which is in communication with a tank or other source of oil-supply. This hanger is formed with a vertical passage 0, as shown, and is constructed with an enlarged rounded lower end.

D represents an oscillating oiler, which is formed with a rounded depression in its upper end which fits the lower end of the hanger B and to which the same is pivotally secured by the pivot E. A tight swinging joint is thus formed between the membersA and D. The oiler D is provided with a vertical oil-passage F, which is forked at its upper end, as shown, so that when the parts A D are in line the passages formed therein will not be in line. The position referred to is that shown in Fig. 1.

The extended end of the pivot E is provided with a vertical slot, and secured therein is the low the end of the said oiler, as shown. This spring serves to hold the parts A D normally in line, and the oiler when thrown to either one side or the other will assume the said position when free to do so.

J represents the oil-cup on the driving or crank shaft, which transmits oil to the bearing. Extending upward on opposite sides of this cup are the posts K, and extending across the top of the cup and secured to these posts is the round bar L, upon which is mounted the roller M.

When the crank carrying the oil-cup is in its highest position when revolving, the roller M on the bar L strikes the lower end of the depending spring and moves the oscillating oiler to one side until the crank has passed sufficiently far to carry the bar out of engagement with the spring end, when the spring will force the oiler back to its normal position. While the oiler is thrown aside, as described above, the vertical passages in the respective partsA D register, and oil is thus free to pass from the former through the latter and drop into the oil-cup, as will be readily understood. One of the forks of the passage in the oiler serves to pass the oil when the crank is moving inone direction and the other fork passes the oil when the motion is reversed. Thus it will be seen thatwhile the driving or other wheel is in motion the crank carried thereby will be constantly supplied with oil, no matter how fast the wheel may be moving, and that when the said wheel is at rest the passages passing the oil, being out of register, will stop the flow of oil until the wheel is again set in motion.

While a flat hanger and oiler in cross-sec- 5 tion are here shown, I do not wish to limit myself to this particular form, as a joint resembling a ball and socket may be used with equal effect and without departing from the spirit of my invention. In like manner the oil-cup, which is here shown as oblong, may be made circular or in any other preferred form.

Having thus described my invention, I claim- 1. In a lubricator, the combination of a perforated hanger formed with a rounded lower end, a perforated oiler having a rounded depression in its upper end and which is pivotally connected to the hanger, and a laterallymoving bearing which engages the oiler, vibrating the same, whereby oil is passed therethrough from the said hanger, substantially as shown and described.

2. In a lubricator, the combination of a perforated hanger, a perforated oiler pivoted thereto, a spring secured at its opposite ends to the hanger and oiler, respectively, and a laterally-moving bearing which engages the oiler, vibrating the same, whereby oil is passed therethrough from the said hanger, substantially as shown and described.

3. In a lubricator, in combination, a perforated hanger having a rounded lower end, a perforated oiler having a rounded depression in its upper end and which is pivotally connected to the said hanger, a spring having a rigid connection at its upper end with the hanger and its depending end connected to the said oiler, an oil-cup mounted on the bearing which is to be lubricated, and a stop on the said cup which is adapted to engage the 1 depending end of the spring, and thus oscillate the oiler, substantially as shown and de scribed.

4:. In a lubricator, in combination, a perforated hanger having a rounded lower end, a perforated oiler having a depression in its upper end and which is pivotally connected to the said hanger, the said oiler being formed with a vertical passage having a forked upper end, a spring secured atits opposite ends to the hanger and oiler, respectively, an oilcup on the bearing to be lubricated, and a bar secured across the said cup which engages the depending end of the spring, whereby the said conveyor is oscillated, substantially as shown and described.

5. In a lubricator, the combination, with a perforated hanger and a perforated oiler, of a pivotal bolt connecting the same, the said bolt being provided with a slot in its extended end, and a spring which is secured between its ends in the said slot and which is secured at its ends to the said hanger and conveyer,

respectively, substantially as shown and described.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN GREER. Witnesses:
